Some physical and mechanical properties of titanium alloys bring great difficulty to cutting. The deformation coefficient of titanium alloy is small during cutting, which increases the sliding friction distance of chips on the rake face and accelerates tool wear. The thermal conductivity of titanium alloy is small, and the heat generated during cutting is not easy to be transmitted, and is concentrated in a small area near the cutting edge. The elastic modulus of titanium alloy is small, and it is easy to bend and deform under the action of radial force during processing, causing vibration, increasing tool wear and affecting the accuracy of parts. Due to the strong chemical affinity of Grade 3 Pure Titanium Plate for tool materials, under the conditions of high cutting temperature and large cutting force per unit area, the tool is prone to bond wear.
